I took Plan B 22 hours later and got spotting then a week later my normal period. I'm now worried because of what's happening before my second period. There's a week until my second period to come, but I have had horrible pls symptoms that i usually never get. I do get sore breasts but now I always have a little bit of pain in my stomach, shortness of breath, and sore breasts. Is this normal? I know plan b can cause hormonal imbalance but I'm just seeing if I should be worried?
